A certain shampoo is available in two sizes. A 14.2- ounce bottle costs $4.98. A 23.7- ounce bottle costs $6.97. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent
Answer:
the 23.7 ounce bottle is the better price because the 14.2 ounce bottle is $0.35 and the 23.7 ounce bottle is $0.29.
Step-by-step explanation:
you simply divide the cost by the ounces and get the unit price
To find the unit price for each size, divide the cost of the shampoo by the number of ounces. The 23.7-ounce bottle is the better buy based on the lower unit price.
Explanation:To find the unit price for each size, divide the cost of the shampoo by the number of ounces in each bottle. For the 14.2-ounce bottle, the unit price is $0.35 per ounce ($4.98 / 14.2). For the 23.7-ounce bottle, the unit price is $0.29 per ounce ($6.97 / 23.7).
To determine which size is the better buy based on the unit price, compare the unit prices. Since the 23.7-ounce bottle has a lower unit price ($0.29 per ounce) compared to the 14.2-ounce bottle ($0.35 per ounce), the larger size is the better buy.

Which expression is equivalent to? Please help! Screenshots attached.
Answer:
[tex]\frac{\sqrt{5} }{x^{2} y}[/tex]
Step-by-step explanation:
That's a complex expression, let's simplify it, step by step, off the start, we'll simplify the 55/11:
[tex]\sqrt{ \frac{55 x^{7} y^{6} }{11 x^{11} y^{8} } } = \sqrt{ \frac{5 x^{7} y^{6} }{x^{11} y^{8} } }[/tex]
Then we'll simplify the x's and y's:
[tex]\sqrt{ \frac{5 x^{7} y^{6} }{x^{11} y^{8} } } = \sqrt{ \frac{5}{x^{4} y^{2} } }[/tex]
Let's split the square root in two and solve the bottom part:
[tex]\sqrt{ \frac{5}{x^{4} y^{2} } } = \frac{\sqrt{5} }{\sqrt{x^{4} y^{2}} } = \frac{\sqrt{5} }{x^{2} y}[/tex]
The solution is then:
[tex]\frac{\sqrt{5} }{x^{2} y}[/tex]
The expression which is equivalent to the given expression is:
[tex]\dfrac{\sqrt{5}}{x^2y}[/tex]
Step-by-step explanation:We are given a expression as:
[tex]\sqrt{\dfrac{55x^7y^6}{11x^{11}y^8}}[/tex]
Now we know that:
[tex]55=11\times 5[/tex]
Hence, we get:
[tex]\sqrt{\dfrac{55x^7y^6}{11x^{11}y^8}}=\sqrt{\dfrac{11\times 5x^7y^6}{11x^{11}y^8}[/tex]
which is written as:
[tex]\sqrt{\dfrac{5x^7y^6}{x^{11}y^8}}[/tex]
Also, we know that if n>m
Then
[tex]\dfrac{a^m}{a^n}=\dfrac{1}{a^{n-m}}[/tex]
Hence, we have the expression as:
[tex]=\sqrt{\dfrac{5}{x^{11-7}y^{8-6}}}\\\\\\=\sqrt{\dfrac{5}{x^4y^2}[/tex]
This could be given as:
[tex]=\dfrac{\sqrt{5}}{\sqrt{x^4}\sqrt{y^2}}[/tex]
Now, we know that:
[tex]\sqrt{x^4}=\sqrt{(x^2)^2}=x^2\\\\and\\\\\sqrt{y^2}=y[/tex]
Hence, we get that:
[tex]\sqrt{\dfrac{55x^7y^6}{11x^{11}y^8}}=\dfrac{\sqrt{5}}{x^2y}[/tex]
Find the value of x. Write your answer as a decimal.
ANSWER
[tex]x = 75.5 \degree[/tex]
EXPLANATION
Lines WO and WX are tangents to the circle.
The angle subtended at the center, Z by minor arc XO is the angle subtended at the circumcenter by the same arc.
Therefore the central angle is 2x°.
The two radii ZX and ZO meets the tangents at right angles.
This implies that:
[tex]2x + 90 + 90 + 29 = 360 \degree[/tex]
Or
[tex]2x + 29 = 180 \degree[/tex]
[tex]2x = 180 - 29[/tex]
[tex]2x = 151[/tex]
Divide both sides by 2
[tex]x = \frac{151}{2} = 75.5[/tex]
The value of x using the quadratic equation is 0.00139. When adjusting exponential notations, move the decimal left or right, depending on whether the exponent is positive or negative. Verifying precision to a certain number of decimal places can be achieved by altering the increment and observing changes beyond the desired precision.
Explanation:To find the value of x when using the quadratic equation, we have two potential solutions, which are x= -0.0024 and x= 0.00139. In practical applications, a negative result may not be viable, which indicates that x would equal to 0.00139. When dealing with exponential notation, moving the decimal to adjust for the exponent is necessary. For instance, 4.5 x 10¹ would become 0.45 when the decimal is moved one place to the left. Similarly, 1.6 x 10² would adjust to 160 by moving the decimal place to the right two places. Conversely, a negative exponent like in 2.4 x 10⁻² requires moving the decimal to the left twice to get 0.024. Understanding this concept is crucial when working with numbers written in scientific notation.
If we're verifying to three decimal places and see a change beyond the third decimal (such as with Ax=10⁻⁵ resulting in 1.00001), we can deduce that the initial three decimal places are indeed accurate. Hence, an answer like 1.00001 confirms that 1.000 is valid up to three decimal places. Additionally, using Newton's method can improve approximations, such as refining an initial estimate of the solution to tan x = x from about 4.5 to a more precise six decimal places.

If x2 + mx + m is a perfect-square trinomial, which equation must be true?
x2 + mx + m = (x – 1)2
x2 + mx + m = (x + 1)2
x2 + mx + m = (x + 2)2
x2 + mx + m = (x + 4)2
The answer is:
The third option,
[tex]x^{2}+mx+m=(x+2)^{2}[/tex]
Why?We are looking for an equation that establishes a relationship between the perfect-square trinomial and the givens notable products.
So, we are looking for a notable product that gives us a value of "m" that is the coefficient of the linear term (x) and it's also the constant term.
- Trying with the two first options, we have:
[tex](x+1)^{2}=x^{2}+2x+ 1\\\\(x-1)^{2}=x^{2}-2x+ 1[/tex]
We can see that for these first two options, the value of m has not the same value for the coefficient of the linear term and the constant term since m is equal 2 and the constant number is not 2.
- Trying with the third option, we have:
[tex](x+2)^{2}=x^{2}+2*(2*x)+2^{2}=x^{2} +4x+4[/tex]
Now, we can see that the value of m is the same for the coefficient of the linear term and the constant term, we can see that m is equal to 4.
So, the correct option is the third option, because
[tex]m=4[/tex]
[tex]x^{2} +mx+m=(x+2)^{2}=x^{2} +4x+4=x^{2} +mx+m[/tex]

The levels of mercury in two different bodies of water are rising. In one body of water the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year.
Answer:
y=6
Step-by-step explanation:
The complete question is as follows:-
The levels of mercury in two different bodies of water are rising. In one body of water, the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water, the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year. Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury?
An equation can be used to find y, the year in which both bodies of water have the same amount of mercury will be given as below:-
0.05 + 0.1y = 0.12 + 0.06y
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Here, we want to find y which is the heat in which the amount of mercury in each of the water bodies is the same.
Now for the first water body:
Initial is 0.05 ppb and after y years, we have a rise of 0.1 x y = 0.1y ppb
So the amount of mercury in ppb after y years would be;
0.05 + 0.1y
For the second water body;
Initial is 0.12 and a rise of 0.06 ppb per year for y years. The rise would be
0.06 x y = 0.06y
So the total amount of mercury here is
0.12 + 0.06y
So to find y which is the year the amount of mercury in each water body is the same, we simple equate both and that would be;
0.05 + 0.1y = 0.12 + 0.06y
Therefore an equation can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y

ln how many ways 5 person sitted in a round table having 8 seats?
Answer: First consider the case that ‘just’ 5 persons are seated around a round table.
Clearly, ‘just’ 5 persons can be seated around a round table in (5 - 1)! = 4! = 24 ways.
Now, one vacant chair is to be inserted among them.
Say, for a particular sitting arrangement ‘ABCDE’; there are 5 scopes available for inserting the vacant chair - between A and B, between B and C, between C and D, between D and E & between E and A.
So, there are 5*24 = 120 ways available that 5 persons can sit around a round table with 6 chairs.

Two numbers have a difference of 28. What is the sum of their squares if it is a minimum?
Answer:
392
Step-by-step explanation:
Squares get really big very quickly, so you don't want to use any bigger numbers. The biggest total of the squares would be from
using
1 and 28
1+28
2=1+784=785
2 and 27=4+729=733
142+14
2=196+196=392
The greater the difference between the two numbers, the bigger one of the numbers is going to be.
Therefore use two numbers with the smallest difference between them which will be
14 and 14
The minimum value of sum of their square is 392.
What is an equation?A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.
Let the Bigger no. = x
Let the Smaller no. = y
x - y = 28 (given)
(x - y)^2 = 28^2
x^2 + y^2 - 2xy = 784
x^2 + y^2 = 784 + 2xy
Let the value of x = 14 and y = -14 (By trial and error)
Hence, the minimum value of sum of squares will be 14^2 + 14^2 = 392.
